İsmail Türker | Mehmet Akif Boz | Hulusi Ozan Taşkesen | Serdar Kamanlı
This research was conducted for 42 days, in order to determine the effects of fluctuate lighting program on production and carcass characteristics of broiler chickens. 300 day old Ross 308 chicks were used. Chicks were randomly distributed to 2 lighting groups which were normal lighting (control) and fluctuate lighting, and each group was divided in to 3 replicates containing 50 chicks. For both groups lighting was arranged as 23 hours of lighting versus 1 hour of dimming. Control group was subjected to constant lighting of 20 lux/m2 for the days 0-21, and 5 lux/m2 for the days 22-42; while in the fluctuate lighting group was subjected to lighting of 5 lux/m2 for 45 minutes and additional 20 lux/m2 for 15 minutes every hour. There were no differences of final body weight, weekly body weight gain, cumulative feed intake, cumulative feed conversion ratio, viability, foot and leg problems, hot and cool carcass weight, thigh weight, breast weight, wing weight, back weight, liver or heart weights. However, there were statistically significant differences of gizzard weight and abdominal fat weight between two groups. In conclusion, gizzard and abdominal fat weights of broilers subjected to fluctuate lighting are less than control. This suggests that fluctuate lighting can be used to lower abdominal fat which is an important problem in broilers.
Afficher plus [+] Moins [-]Influence of Conventional Fermentation on Antioxidant Activity and Phenolic Contents of Two Common Dairy Products: Yogurt and Kefir
2020
Bilge Taşkın | Neriman Bağdatlıoğlu
During conventional fermentation of milk into yogurt and kefir, changes of antioxidant capacities (DPPH radical scavenging, ferrous chelating, reducing power, hydrogen peroxide/ H2O2 scavenging activity) and total phenolic content were investigated. Both products showed greater phenolic content, DPPH radical scavenging, and reducing power activities than was the case of their unfermented milk forms. But they were unable to scavenge H2O2. Chelating ability of milk increased by yogurt fermentation but decreased by kefir fermentation. In general, antioxidative capacity of milk improved throughout conventional yogurt and kefir fermentations and ripening periods (except chelating ability for kefir and H2O2 scavenging). This study is valuable since it evaluates the antioxidant power of yogurt and kefir produced by traditional fermentation with 5 different antioxidative approaches. In face of rapidly rising consumer demand for safe, healthy, functional but natural foods, revealed results might strengthen importance of conventional fermentation process and highlight the antioxidative contributions of mentioned products
